' To @ZZ whom t may concern:

- Be it known that I, WILLIAM C. HEIMER- DINGER, a resident of Louisville, vin the'county of Jefferson and State of Kentucky, have in- Vented certain new and useful Improvements in Machinesforsharpening Razors; and I do` hereby declare the ollo'wing to be a full,

, clear, and exact description of the invention,

such as will enable others skilled in the art to which it'appertains to make and use the same. My invention relates to improvements in a i machine for sharpening razors, the object of f vide improved the invention being to provide an improved .razor-clamp so constructed that it will hold all razors of standard make, regardless of size,

with their cutting edge in thesame plane to be properly presented to the rolls and .pro-

means for'feeding the razor back and forth and improved means for shifting;l the razor-from side to side and exert-4 ing varying pressure thereon.

Wit-h these and other objects in view the inventLon consists in certain novel features Iof construction and combinations and arrangements of parts, as will be more fully 4 hereinafter described, and pointed out in the claims. y In the accompanying drawings, Figures 1 and 2 'are views in cross-section, illustrating my improvements.` Fig.y 3 is a view in ele-- vation, and Figs. 4, 5, 6, and 7 are detail views, illustratingthe blade-holder- 1 represents a4 table or frame roviding mounting thereon` for a horizontal s aft 2,v on which sharpening-rolls 3 3: are secured and provided on their opposite faces with leather, stone,` orrotherlinaterial to strop, hone, or grind a blade, and, in fact, machines will .be provided containing all the stones and hone necessary to put the best ossible edge on the razor, and it will be und) these rolls vare hereinafter'r'eferred to` as sharpeningerolls it is .intended to cover all material forthe purpose.v y

A lever 4 is fulcrumed at its/lower end on a rod 5 and carries a' frame 6 at its upper end, made with alined bearings for a'shaft 7, located at richt angles to. lever.4, and t'o thev inner endozf this shaft my improved razorclamp, is secured andwill be more fully hereinafter described.

The" outer end of shaft 7 has a depending arm onplate secured thereon, and the latter is madeI '.vith'abifurcated-lu 9 to receive a long thin springfbar 10', whi latter extends through a3 slotted Enger 11, adjustablyse l 'Specification'of Letters Patent. l l l Application led Deceinbe` 7.1905.

l cured lon an upright rod 12,4 carried by a horil 13, mounted to zontal reciprocating rod slide in bearings in frame 1 l f The-frame 1 also supports a drive-shaft 14, having a drive-pulley thereon, and a belt 16 transmits motion from a pulley 17 on driveshaft 14 to onemember of a friction clutch-v pulley 18 on a short shaft 19, and the other member 18a of said friction clutch-pulley 18 is connected by a belt 20 with a pulley 21 on a short shaft 22. The friction clutch-pulley 18 -is provided with an operating-bar 23, connected lwith any approved -treadle mechan-` ism to permit the member 18a of clutch 18 to be held to stop the niovement'of the razor.

Patented nec. 25,1906'.

.Short shaft 22- is provided at one end` I with anv adjustable crank-arm 24, connected by a link 25 with lever 4 to swing the latter v back and `forth and move the razor in and out between the sharpening-rolls, which latter are continuously driven by a belt connecting a pulley 27 on the drive-shaft with a pulley 28 on shaft-2. A belt 29 connects a pulley 30 on the drivea worm-shaftg32, the worm on the latter shaftmeshing with a worm-wheel 33 on a cross-shaft 34, which latter carries at its end an adjustable cranking lever 37, pivotally end and connected at 38 on the reciprocating'bar 13. t

' My improved razor-clamp above referred to is constructed as followsi 'The razor-clamp comprises a metal block 39, secured to the arm 35, -connected by a link 36 with a swing! supported at itsupper end of shaft 7 bya bolt 40 and nut, as shown,

and is made with inclined sides to receive plates 41, secured thereto-'by screws or otherwise. The block 39 about midway its its lower end to an arm length is made with an opening to receive a slidingpinY 42, secured'at its u per endto a bar .43, movable between l) zor-blade, and the block 39 isgrooved to receive this bar 43 when in its lowest position. The lower end of pin 42 projects through an opening in an operating-lever cross-pin 45 below the saine, so that when lever 44 is forced down the bar 43 -willbe drawn down with it, .and a wire spring 45a, supported on theblock 39, is connected at one end to pin 42to exert `upward pressure on bar to force the -razorup into proper position in the holder. As'v all'razors of standard make have the` samer'elative width of base in accordance with the width of the IOQ 44 and has la IIO ZCI

blade to give the same angle of pitch to the blade when laid flat, and as the side plates of the clamp are located at this standard pitch, the edge of each and every standard razor will be held by the clamp in precisely the same position, for if it be a narrow blade it will have a correspondingly narrow base and will be projected farther upward by the bar 43. The razors are slid between -the side plates of the clamp at one end, and said side plates may have clamping-fingers, as shown, or these fingers may be dispensed with, a's desired.

The operation is as follows: The sharpening-rolls are turned continuously, and when a razor is in the clamp and the clutch-pulley 18 permitted to operate lever 4 will be swung inward and outward to move the razor in and out between the rolls, and the rod 13 will be reciprocated by the mechanism above eX- .plained to tilt the razor from` side to side.

By employing the flexible spring-bar 10 it will be seen that the blade will first, lightly touch one roll, and as the rod 13 continues to move and bow the spring-bar 10 pressure of the razor against the roll will be gradually increased until the maximum is reached, when the rod begins to movein the opposite direction, thereby gradually reducing the pressure until the minimum and moving the razor over to engage the otlier roll, and so on, thus carrying out the correct o eration of handsharpening with perfect an regular manipulation to produce the best possible edge.

' Slight changes might be made in the general form and arrangement of the parts described without departing from my invention, and hence I do not restrict myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claimas new, and desire to secure by Letters Patent, is=
